Ethernet Connectivity


Webpage & Service Software

Model 375s equipped with the Ethernet option offer more advantages. Up to 50 area monitors can be connected to a radiation network that collects and displays radiation levels along with the status of the alarm. A standard webpage browser can, with appropriate authorization, view all data across the network and audibly annunciate any alarms. The system may also be configured to send intelligent email alerts to responsible personnel, and capture an image of whatever triggered the alarm, when optional Ethernet cameras are employed.
